One-step Diffusion with Distribution Matching Distillation

no code implementations30 Nov 2023 Tianwei Yin, Michaël Gharbi, Richard Zhang, Eli Shechtman, Fredo Durand, William T. Freeman, Taesung Park

We introduce Distribution Matching Distillation (DMD), a procedure to transform a diffusion model into a one-step image generator with minimal impact on image quality.

FastComposer: Tuning-Free Multi-Subject Image Generation with Localized Attention

1 code implementation17 May 2023 Guangxuan Xiao, Tianwei Yin, William T. Freeman, Frédo Durand, Song Han

FastComposer proposes delayed subject conditioning in the denoising step to maintain both identity and editability in subject-driven image generation.

Learning Task-Specific Strategies for Accelerated MRI

no code implementations25 Apr 2023 Zihui Wu, Tianwei Yin, Yu Sun, Robert Frost, Andre van der Kouwe, Adrian V. Dalca, Katherine L. Bouman

Traditional CS-MRI methods often separately address measurement subsampling, image reconstruction, and task prediction, resulting in a suboptimal end-to-end performance.

Global Tracking Transformers

1 code implementation CVPR 2022 Xingyi Zhou, Tianwei Yin, Vladlen Koltun, Philipp Krähenbühl

The transformer encodes object features from all frames, and uses trajectory queries to group them into trajectories.

Multimodal Virtual Point 3D Detection

1 code implementation NeurIPS 2021 Tianwei Yin, Xingyi Zhou, Philipp Krähenbühl

For autonomous driving, this means that large objects close to the sensors are easily visible, but far-away or small objects comprise only one measurement or two.

End-to-End Sequential Sampling and Reconstruction for MRI

1 code implementation13 May 2021 Tianwei Yin, Zihui Wu, He Sun, Adrian V. Dalca, Yisong Yue, Katherine L. Bouman

In this paper, we leverage the sequential nature of MRI measurements, and propose a fully differentiable framework that jointly learns a sequential sampling policy simultaneously with a reconstruction strategy.

Detecting Adversarial Examples via Neural Fingerprinting

1 code implementation11 Mar 2018 Sumanth Dathathri, Stephan Zheng, Tianwei Yin, Richard M. Murray, Yisong Yue

Deep neural networks are vulnerable to adversarial examples, which dramatically alter model output using small input changes.
